Hello Eli Cohen,
The patch e126ba97dba9: "mlx5: Add driver for Mellanox Connect-IB
adapters" from Jul 7, 2013, leads to the following Smatch warning:
"drivers/net/ethernet/mellanox/mlx5/core/cmd.c:822
mlx5_alloc_cmd_msg()
warn: use 'flags' here instead of GFP_XXX?"
811 static struct mlx5_cmd_msg *mlx5_alloc_cmd_msg(struct mlx5_core_dev
*dev,
812 gfp_t flags, int size)
^^^^^^^^^^^
813 {
814 struct mlx5_cmd_mailbox *tmp, *head = NULL;
815 struct mlx5_cmd_prot_block *block;
816 struct mlx5_cmd_msg *msg;
817 int blen;
818 int err;
819 int n;
820 int i;
821
822 msg = kzalloc(sizeof(*msg), GFP_KERNEL);
^^^^^^^^^^
823 if (!msg)
824 return ERR_PTR(-ENOMEM);
825
826 blen = size - min_t(int, sizeof(msg->first.data), size);
827 n = (blen + MLX5_CMD_DATA_BLOCK_SIZE - 1) /
MLX5_CMD_DATA_BLOCK_SIZE;
828
829 for (i = 0; i < n; i++) {
830 tmp = alloc_cmd_box(dev, flags);
^^^^^
There is a kmalloc() in alloc_cmd_box() that uses flags as well as a
pci_pool_alloc() that uses it.
831 if (IS_ERR(tmp)) {
832 mlx5_core_warn(dev, "failed allocating
block\n");
regards,
dan carpenter
